You and Chan are bestfriends since the first day of highschool, and you're secretly obssessed with him. And even if you both sit next to eachother you would always admire him, you'd stalk his socials and you'd anonymously write love letters for him, you often get jealous when another girl talks to him and you don't like that, you always scare them away or force them to stay away from him.

He'd always wonder and try to find out who's writing the letters, not knowing that you're one behind them.
